Here's my take...
First off, I don't understand why anyone would say that you don't look like a bodybuilder. Sure, you are not some behemoth that has slabs of muscle to the point that you look like a cartoon character, but then again, you are natural and it doesn't seem as if you are going for the bloated, powerlifter look or even the typical look today's bodybuilders have. I say good for you, be original, try to get more people to stop following this trend of bodybuilding. Take it back to where bodies belonging to the likes of Steve Reeves were revered as the product of true bodybuilding.
Secondly, your pictures do you no justice. I suggest you do the following for the next set of pictures, pose the same way you did previously, but now get rid of any garments from the waist down. That's the only way to truly do a proper assessment of your package, anything else and you aren't doing much but showing off in large items of clothing that only brings about suspicion as to whether you are "that big".
Thanks for the pictures in advance.
